Vocal Sac
The vocal sac is the flexible membrane of skin possessed by most male frogs and toads. The purpose of the vocal sac is usually as an amplification of their mating or advertisement call. The presence or development of the vocal sac is one way of externally determining the sex of a frog or toad in many species; taking frogs as an example; The vocal sac is open to the mouth cavity of the frog, with two slits on either side of the tongue. To call, the frog inflates its lungs and shuts its nose and mouth. Air is then expelled from the lungs, through the larynx, and into the vocal sac. The vibrations of the larynx emits a sound, which resonates on the elastic membrane of the vocal sac. The resonance causes the sound to be amplified and allows the call to carry further. Muscles within the body wall force the air back and forth between the lungs and vocal sac. Development The development of the vocal sac is different in most species, however they mostly follow the same process. The d ...

Amphibians Of Bhutan
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic ...

Scutiger (toad)
''Scutiger'' is a genus of toads in the family Megophryidae. Common name lazy toads has been coined for them. They occur in China, Burma, Nepal, and northern India in high-altitude habitats. Most are endemic to China. Evolution A 2017 molecular phylogenetic study found that ''Scutiger'' originated in Paleo-Tibet during the Oligocene. Species The following species are recognised in the genus ''Scutiger'': * '' Scutiger adungensis'' Dubois, 1979 – Adung lazy toad * '' Scutiger bhutanensis'' Delorme and Dubois, 2001 * ''Scutiger boulengeri'' (Bedriaga, 1898) – Boulenger's lazy toad, Xizang alpine toad, Himalayan stream frog * '' Scutiger brevipes'' (Liu, 1950) * ''Scutiger chintingensis'' Liu and Hu, 1960 – Chinting lazy toad, Chinting alpine toad * ''Scutiger ghunsa'' Khatiwada, Shu, Subedi, Wang, Ohler, Cannatella, Xie, and Jiang, 2019 – Ghunsa high altitude toad * '' Scutiger glandulatus'' (Liu, 1950) – Hopachai lazy toad, chest gland cat-eye ...

Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate Osteological correlates are marks on the bones of animals that are made from the causal interactions of the soft-tissue Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bo ... such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toad
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. A distinction between frogs and toads is not made in scientific taxonomy, but is common in popular culture (folk taxonomy), in which toads are associated with drier, rougher skin and more terrestrial habitats. List of toad families In scientific taxonomy, toads include the true toads (Bufonidae) and various other terrestrial or warty-skinned frogs. Non-bufonid "toads" can be found in the families: * Bombinatoridae ( fire-bellied toads and jungle toads) * Calyptocephalellidae (helmeted water toad and false toads) * Discoglossidae ( midwife toads) * Myobatrachidae (Australian toadlets) * Pelobatidae (European spadefoot toad) * Rhinophrynidae ( burrowing toads) * Scaphiopodidae (American spadefoot toads) * Microhylidae ( narrowmouth toads) Biology Usually the largest of the bumps on the skin ...

Nyingchi Prefecture
Nyingchi (), also known as Linzhi and as Nyingtri, is a prefecture-level city in the southeast of the Tibet Autonomous Region in China. The administrative seat of Nyingchi is Bayi District. Nyingchi is the location of Buchu Monastery. Economy Tourism The average elevation of Nyingchi is 3,040 meters (9,974 feet), which is the lowest compared with the other prefectures in Tibet. So, the risk of getting high-altitude sickness is relatively lower than other parts on the plateau. Guangdong province announced in 2012 that it plans to invest more than RMB 400 million (US$63 million) in Nyingchi's tourism industry. According to the plan, Guangdong will help build 22 "prosperous model villages" in Nyingchi in counties such as Bomê County, Bomê and Zayü County, Zayü. Transportation It takes about 5 hours to travel from Lhasa to Nyingchi by a highway opened at the end of 2018. Nyingchi is connected to Lhasa by the 435-kilometer Lhasa–Nyingchi railway, completed in 2021. The jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
